css transition-timing-function attribute syntax
Function:The transition-timing-function attribute specifies the speed curve of the transition effect. This property allows the transition effect to change its speed over time.
Syntax: transition-timing-function: linear|ease|ease-in|ease-out|ease-in-out|cubic-bezier(n,n,n,n) ;
Description: linear specifies the transition effect that starts and ends at the same speed (equal to cubic-bezier(0,0,1,1)). Ease specifies the transition effect that starts slowly, then becomes faster, and then ends slowly (cubic-bezier(0.25,0.1,0.25,1)). Ease-in specifies a transition effect that starts at a slow speed (equal to cubic-bezier(0.42,0,1,1)). Ease-out specifies a transition effect that ends at a slow speed (equal to cubic-bezier(0,0,0.58,1)). ease-in-out specifies a transition effect that starts and ends at a slow speed (equal to cubic-bezier(0.42,0,0.58,1)). cubic-bezier(n,n,n,n) Define your own values in the cubic-bezier function. Possible values are between 0 and 1.
Note: Internet Explorer 10, Firefox, Opera and Chrome support the transition-timing-function attribute. Safari supports an alternative -webkit-transition-timing-function attribute. Note: Internet Explorer 9 and earlier browsers do not support the transition-timing-function attribute.
